Local installation of Grew-match

Grew-match is available online on a set of corpora (mainly from the UD project). If you want to use Grew-match on your own corpus, you have to install it locally, following the instructions on this page.

The daemon

You have to start locally a daemon which will handle your requests on your corpora.


Follow general instruction for Grew installation and then install the daemon with:

opam install grew_daemon


To configure your daemon, you have to describe the corpora you want to use in a conf file. This file describes each corpora with a name, a directory and a list of files. For instance, the JSON file my_corpora.json below defines 3 corpora:

{ "corpora": [
  { "id": "my_corpora",
    "directory": "/users/me/corpora/my_corpora",
    "files": [ "my_corpora_dev.conll", "my_corpora_test.conll", "my_corpora_train.conll" ]
  { "id": "my_corpora@2.0",
    "directory": "/users/me/corpora/my_corpora/2.0",
    "files": [ "my_corpora_dev.conll", "my_corpora_test.conll", "my_corpora_train.conll" ]
  { "id": "my_corpora@1.0",
    "directory": "/users/me/corpora/my_corpora/1.0",
    "files": [ "my_corpora_dev.conll", "my_corpora_test.conll", "my_corpora_train.conll" ]

Compile your corpora

In order to speed up the pattern search and to preserve memory when a large number of corpora are available, corpora are compiled with the command:

grew_daemon marshal my_corpora.json

A new file with the name of the corpus and the extension .marshal is created in the corpus directory. Of course, you will have to compile again if one of your corpora is modified. You can clean the compiled files with

grew_daemon clean my_corpora.json

Run the daemon

The Daemon is started with the command (update the port number if necessary):

grew_daemon run --port 8888 my_corpora.json

STEP 2: install the webpage


The code for the webpage is available through gitlab.inria.fr with:

git clone https://gitlab.inria.fr/grew/grew_match.git


Edit the file grew_match/corpora/groups.json to describe the set of corpora available. For instance with our previous examples with 3 corpora, the configuration file looks like:

{ "groups": [
    { "id": "local",
      "name": "Local corpora",
      "corpora": [
        { "id": "my_corpora" },
        { "folder": "Older versions",
          "corpora": [
            { "id": "my_corpora@2.0" },
            { "id": "my_corpora@1.0" }

In JSON, groups define the items in the top navbar and corpora the list of corpora in the left bar, maybe organised in folders (recursive folders are not handled). You can look the configuration file used on Grew-match for a larger example.


Edit the following installation script (update DEST definition and port number id needed). Run it from the place where you did the git clone.

# decide where you want to store the webpage locally

# Copy the files in the right place
cd grew_match
cp -rf * $DEST

# build local folders for storing data
cd $DEST
mkdir -p data/shorten
chmod -R 777 data

# update parameters in the code
sed -i old "s+@PORT@+8888+" ajaxGrew.php
sed -i old "s+@DATADIR@+$DEST/data/+" ajaxGrew.php
sed -i old "s+@DATADIR@+$DEST/data/+" purge.php
sed -i old "s+@DATADIR@+$DEST/data/+" shorten.php
rm -f *old

Step 3 and more


You should be able to request your corpora from localhost. Feel free to contact us in case of trouble.

Restart the daemon when one of the corpora is updated

  1. Kill the running daemon (you can use the command killall grew_daemon if the daemon is running in the background)
  2. Run the compile operation again: grew_daemon marshal my_corpora.json
  3. Restart the daemon: grew_daemon run --port 8888 my_corpora.json
